Integrated electrical and low-voltage systems of all types—inside and outside a building—encompass the range of work that electrical contractors do. The articles in this section highlight different types of work, from security, fire and life safety, to traditional electrical power and distribution, to lighting, cabling and more. 

The quote “The more I learn, the more I realize how much I don’t know,” is popularly attributed to Albert Einstein.

Commercial building energy codes impose design standards for nonresidential buildings’ energy efficiency. Many states have implemented an energy code to regulate building design.

For many of us, these are technologically challenging times. Just when I think I have mastered the latest smartphone, it changes. Prepare yourself, because, just like mobile devices, the codes and standards are morphing in ways you might not expect.

When manufacturers are asked what is the biggest problem with installing of fiber optic components and systems, they invariably say “testing.” Practically everything they do depends on testing. During development, engineering and manufacturing in their labs, they test product performance.

Help Is On the Way

Look for a new fiber test bulletin (not a standard) from the Telecommunications Industry Association (TIA ) in 2003. We all know fiber is looked at as more difficult to work with, so maybe that is why a new guidance bulletin is coming out that better describes fiber testing in the field.

Opportunities and Challeges Continue to Grow in the Fire/Life Safety Systems Market

The estimated installed market value of fire alarm systems in commercial facilities is valued at nearly $3.3 billion. It is estimated that systems installers account for more than half of this market value (55 percent). This information is based in part on the “U.S.

Fiber Optic Cleaving Techniques

A good cleaver helps cut out costly mistakes To get good fiber optic splices or terminations, especially when using the pre-polished connectors with internal splices, it is extremely important to cleave the fiber properly.

'James Bond' Surveillance

Covert “007” techniques are possible James Bond, watch out! Now, many of the techniques employed by the action adventure hero turned cultural icon are possible—especially when it comes to closed-circuit television surveillance (CCTV).
